The cancer that begins in the basal cells is called basal cell cancer or basal cell carcinoma. Benign: not cancerous‚ also called non-malignant. Malignant tumor is a cancerous growth.For example‚ fibroadenoma is a benign tumor of breast whereas as adenocarcinoma is a malignant tumor of the breast. Benign

Example lab report of Synthesis of potassium tris (oxalato) ferrate (III) trihydrate Posted by Nurul Yunaliyana Experiment 5: Synthesis of potassium tris (oxalato) ferrate (III) trihydrate Purpose: to synthesis potassium tris (oxalato) ferrate (III) trihydrate ‚K3 [Fe (C2O4)3].3H2O. Introduction: Ferrous ammonium sulfate‚ Fe(NH4)2(SO4)2.6H2O is dissolved in a slightly acid solution‚ excess oxalic acid‚ H2C2O4‚ is added and the following reaction takes place: Fe(NH4)2(SO4)2.6H2O + H2C3O4

order to evaporate. If the rate of evaporation is occurring faster‚ it indicates it is drawing more heat from the body in order to change its state of matter. Greater heat loss means a greater change in temperature. Thus‚ when the alcohol evaporates‚ the temperature of the skin is dropping and creates a cooling sensation. This shows our body’s sensitivity to temperature loss‚ and the ability to quickly detect it and act accordingly in response‚ to prevent further heat

The Virtual Lab – ELISA Test Lab: Immunology 09/04/2013 Instructors: Dr. Charlie Wilson Written by: Dipen Patel I. Objective: The purpose of the lab was to learn the procedure of performing an ELISA test to determine whether a particular antibody is present in a patient’s blood sample. ELISA is an abbreviation for “Enzyme-linked Immunosorbent Assay." II. Introduction: The interaction of antigen and antibody outside the body can be used to determine if patient

I.Purpose The purpose of this lab is to show how potential energy and kinetic energy is shown and transferred using a model rollercoaster. This lab also demonstrates the Law of Conservation of Energy. II.Introduction Potential and Kinetic energy have a very big relationship. The Law of Conservation of Energy states that “Energy cannot be destroyed or created‚ but can be transformed or transferred.” This lab will help demonstrate this law and show the conversion between Kinetic and Potential

McLean 1 Creating Acetylene Gas Introduction The purpose of the lab was to determine the ratio of air to acetylene results in complete combustion of acetylene gas. The balanced chemical equation for this experiment was C2H2(g) + O2(g) --> CO2(g)+ H2O(l). Complete combustion is the reaction of an element or compound with oxygen to produce the most common oxides and energy. Complete combustion occurs when the fuel and oxygen combine in exact proportions to completely burn the fuel

increasing heart rate. This increase causes a rise in O2 consumption and CO2 production‚ which shows an increase in metabolism. Does this hold true for every animal though? In this experiment we are using lab mice‚ Mus musculus‚ to see if the introduction of a predator scent (fox urine) increases‚ decreases‚ or has no effect on the metabolic rate within them. We will calculate the mass specific metabolic rate and use a t-test to determine if there is a significant change in metabolic rate when the mouse

pharmaceutical compounds on the heart rate of Daphnia specimens. After basal heart rate was observed and computed‚ four different solutions each containing either an adrenergic‚ muscarinic‚ or nicotinic agonist or antagonist was tested against individual Daphnia. Observations were made through a compound light microscope through the 10x objective. It was found that nicotine decreased‚ caffeine increased‚ lidocaine decreased‚ epi decreased basal heart rate. This can be explained secondary to their
